Oryzias latipes var.
Gorgeous variety combining red, white, and black tricolor with elongated fins. Beautiful combination of phoenix-like graceful long fins and complex body coloration. Advanced collector's variety.
Houou (Phoenix) medaka is a luxurious premium improved variety combining red, white, and black tricolor body coloring with long-fin traits. Like the mythical phoenix, its gracefully spreading long fins combined with complex tricolor coloration dramatically elevate ornamental value. Fin movement in side-view tanks is particularly beautiful, while top-view also reveals the tricolor pattern. Fixation of tricolor x long-fin is extremely difficult — producing ideal tricolor distribution with long fins requires mass breeding, advanced selection skills, and years of experience, making this a true advanced hobbyist variety. Gentle current is essential as strong flow damages delicate fins. Carotenoid-rich food maintains red coloration.
